This study taking gestodene (GEST) as a model, investigated the factors affecting reservoir-type intravaginal ring (IVR)'s drug release. This paper reported a gestodene intravaginal ring of reservoir design, comprising a gestodene silicone elastomer core encased in a non-medicated silicone sheath, separately manufactured by reaction injection moulding at 80 degrees C and heating vulcanization at 130 degrees C is reported. The test investigated the factors affecting drug release through a single variable method, taking the drug release rates of 21 days as standards. When changing the thickness of the controlling sheath outside, the ratio of the first day of drug release and mean daily release (MDR), named the relatively burst effect, is closing to 1 with the thickness of controlling sheath increasing, while the 1.25 mm sheath corresponding to 1.04 controlled the burst release effectively; a positive correlation (r = 0.992 2) existed between the average drug release (Q/t) and drug loading (A) within a certain range. The C6-165 controlling sheath with high solubility of GEST is easier to achieve controlled release of the drug; GEST crystalline power is more effective to implement controlled release of drugs among difficent states of the drug. A 1/4 fractional segment core gives a relatively burst effect of 1.76, while the 1/1 and 1/2 are 1.93 and 1.87 separately, at the same drug loading, concluding that use of a fractional segment core would allow development of a suitable GEST reservoir IVR. In summary, GEST reservoir-type IVR could be adjusted by the thickness of controlling sheath, the loading of drug, the material properties of controlling sheath, the dispersion state of drug, the additive composition and structure of intravaginal ring, to control the drug release behavior and achieve the desired drug release rate.

Objective To explore the effects of physiological ischemia training (PIT) on the function of endothelial progenitor cells.Methods Eighteen male New Zealand rabbits (2.5 ± 0.5) kg were divided into 3 groups:a sham operation (SO) group,a myocardial ischemia (MI) group and a MI ± physiological ischemia training (MI ± PIT) group.The PIT was modeled by ischemic isometric contraction of gastrocnemius muscle induced by electric stimulation (40 Hz,1 ms,40% maximum current strength),and the MI was modeled by implantation of a water balloon to occlude the left ventrical branch of the heart.The experiment was conducted for 4 weeks.Before and after the experiments,the ability of mobilization and adhesion of endothelial progenitor cells were detected,the number and the capillary density were counted.Results Post-experiment,compared with groups SO and MI,PIT group significantly improved the ability of mobilization (151 ± 16 cells/HPF,P < 0.01) and adhesion (17.8 ± 2.8 cells/ HPF,P < 0.05),increased the circulating amount (P < 0.05) and capillary density (824.0 ± 106.6 /mm2,P < 0.05).Pearson analyze showed that there was positive correlation between circulating EPCs and capillary density.Conclusion Physiological ischemia training could improve EPCs mobilization and function,resulted to neovascularization in the ischemic heart tissues.

Objective To investigate the clinlic therapeutic result of detenial sigmoid neobladder after radical cystectomy. Methods 50 patients with bladder cancer (41 males and 9 females;age range from 35 to 82 years) were admitted and underwent radical cystectomy and detenial sigmoid neobladder. Results All the 50 patients were followed up for a mean of 18.6 months(range from 6 to 29 months).The blood Cr and BUN levels were both in the normal range without acidosis in all the cases.Only 2 had unilateral ureteral urine reflux during cystography.Of the 50 patients 45 cases(90%) achieved continence during daytime;10 cases(20%) were incontinent at night,but 8 of the 10 cases could control urination by being woken up at night.The capacity of the neobladder was 220 to 550 ml with a mean of 350 ml and the maximal pressure of the neobladder during filling was 15 to 55 cmH 2O(1 cmH 2O=0.098 kPa) with a mean of 35 cmH 2O. Conclusions As a simple operation the detenial sigmoid neobladder can be performed easily with less complications and more reliable results.This operation may be generally applied in clinical practice.

Objective By investigating the departments of ECG and the staff in China,to study the current ECG status and thus provide references for training ECG workers,improving the work environment and stabilizing the ECG professional team.Methods One hundred and twenty four domestie grass-root hospitals were investigated through real-name questionnaire surveys.The data was collected and analyzed.Results Among the 124 investigated hospitals,the educational background description is:(1) The ECG workers in provincial or municipal hospitals had mainly been entitled with Bachelor's degree or above accounting for 72.7% of whole ECG workers;the ECG workers in the county or township hospitals were entitled with college degree or below,accounting for 85.7% of whole ECG workers.The difference between the two kind of workers was significant(P<0.01).(2) The proportion of ECG workers owning senior professional titles in provincial or municipal hospitals and county or township hospitals were both low,which were 12.2% and 3.6%,and the former one was significantly higher than the later(P<0.01).(3) The proportion of hospitals which established dependent department of ECG was low;the percentage of provincial or municipal hospitals was 23.4%,which was significantly higher than that of county or township hospitals (3.3%,P<0.05).(4) The provincial or municipal hospitals were well equipped and also conducted various of inspection projects in comparison to county or township hospitals.Conclusions The grass-root ECG staff in China has no satisfying education background and professional titles;ECG department belonging varies and the special inspection projects are insufficient and the economic benefit was low.So this study suggest that the competent departments take measures in improving ECG personnel enthusiasm,improving the working environment,and ensuring the healthy and orderly development of ECG profession.

BACKGROUND: At present, there is little related report about producing a whole-kidney acellular matrix (ACM) scaffold in rats using perfusion. The cellular biocompatibility of the ACM is poorly understood. OBJECTIVE: To produce a whole-kidney ACM scaffold in rats by perfusion, to evaluate the cytocompatibility of ACM with the L929 cells in vitro, and to assess the possibility of ACM as the cytoskeleton and tissue-engineered urinary organ construction. DESIGN, TIME AND SETTING: An in vitro observation was performed at the Central Laboratory of Zhujiang Hospital, Southern Medical University from February to May 2009. MATERIALS: Kidneys were obtained from 12-week-old Whista rats, while ureter, renal veins and renal artery were reserved. Intravenous catheters were inserted through renal arteries to establish channels for perfusion. Whole-kidney retrograde perfusion was performed with successively heparinized PBS, 1% SDS, deionized water, 1% TritonX-100 and antibiotic-containing PBS under a pressure of 9.81 kPa to prepare whole-kindney acellular matrix scaffolds. METHODS: ① Samples were randomly divided into blank group (without any cells), negative control group (culture media), experimental group (rat kidney ACM leaching liquor), and positive control group (culture media containing 0.64% phenol). L929 cells in the logarithmic phase were seeded in 96-well plates at the density of 4×10~3/well, with 5 wells in each group. At 24, 72, and 120 hours after incubation, cells were stained with MTT method to detect absorbance at 490 nm and calculate relative growth rate. ② Control group (culture medium), experimental group (rat kidney ACM leaching liquor), and positive control group (culture media containing 0.64% phenol) were set up to detect cell apoptosis at 48 hours after culture using flow cytometry. MAIN OUTCOME MEASURES: Microstructure of the scaffold, cytotoxicity and cell apoptotic rate. RESULTS: After SDS and TritonX-100 union processing, reticulate structures made of basilar membrane and collagen were shown under scanning electron microscope rather than normal structures of cells. At every time intervals (24, 72, and 120 hours), there was no significant difference in the absorbance between experimental group and negative control group (P > 0.05). The grade of the cytotoxicity of the ACM was .0-1. There was no significant difference in cell apoptotic rate between experimental group and negative control group (P > 0.05). CONCLUSION: The whole-kidney acellular matrix scaffolds in rat by perfusion have good biocompatibility.
